BACKGROUND OF THE EMBODIMENTS

For centuries, humans have been trying to improve clothing to better suit their needs. This has been done by improving materials and manufacturing techniques. The latest step in innovation has been to use man-made products and materials. However, that has presented other challenges, such a softer more natural feel, stronger and longer lasting performance. Although some natural fibers and materials such and leather and fur have provided humans with softness, warmth and durability in the past, these materials are now very expensive to obtain in large global quantities. A review of related technology presents the following publications.

For instance, U.S. Pub 2016/0032501 pertains to a moisture transfer yarn blend and fabric containing a selected of engineered shaped, lobed, deep grooved, channeled, hollow, sheath-core, bi-component polymer silver fibers and bi-component polymer fibers, optionally blended with cylinder or round fibers or natural fibers or a combination. The engineered shaped, lobed, channeled and deep grooved polymer fibers have indentations along the longitudinal side of the fibers. The deep grooved fibers have four to eight deep indentations along the longitudinal side of the fibers and containing grooves in the deepest portion of the indentation.

U.S. Pub. 2017/0145596 pertains to a cooling material that can include a yarn having a defined denier of less than or equal to approximately 90 denier, wherein the yarn can comprise a cooling additive disposed on or in a polymer. In some embodiments, the yarn can be at least one of a warp or a weft of a woven fabric. Including a polymer, a cooling additive, wherein the cooling additive is disposed on or in the polymer; and processing the cooling material by employing a non-weaving technique to create a non-woven fabric. In some embodiments, the non-weaving technique is one of a melt-blown process, a spun-bond process, or a multi-denier process

However, none of the art described above addresses all the issues that the embodiments of the present invention do. A need still exists for a fiber that improves fiber breakage that is typical in man-made fibers, but at the same time prevents fabric stretching and growth.
